Test Coverage

Chemical & Physical Testing

In-house lab screening first, third-party laboratory re-testing on demand — formaldehyde, pH, colorfastness, heavy metals and drawstring safety controlled batch by batch.

Chemical testing

  • Formaldehyde < 20 ppm
  • pH value 4.0–7.5
  • Colorfastness — saliva & perspiration
  • Heavy metals — lead, cadmium, nickel release
  • Phthalates (6P) < 0.1%
  • Azo dyes (banned amines)

Physical testing

  • Snap & button pull strength — 70–90 N
  • Martindale abrasion — 5,000+ pilling cycles
  • Seam strength & left/right symmetry
  • Drawcord & small-parts safety (choking hazard)
  • Fabric weight & moisture regain — ±0.5 g
  • Needle / metal detection on every piece

In-house Laboratory

Physical & Chemical Testing Lab

18 compliance and safety specialists on site, enforcing rigorous EU, US and Japanese test standards — full screening completed before bulk production.

Infant-grade chemical & physical testing
Songyu in-house physical & chemical testing lab

Universal tensile tester

70–90 N pull force on snaps and buttons, simulating violent pulling. Class A tolerance.

Crock colorfastness tester

Dry and wet rub simulation to prevent chemical transfer risk. Benchmark grade 4–5.

Martindale abrasion tester

5,000+ pilling cycles covering skin-contact and synthetic areas. GB/T 21196.2.

Weight & moisture-regain gauge

Lab-level fabric weight consistency QC, eliminating weight discrepancies. ±0.5 g.

pH & formaldehyde pre-screening

In-house screening before third-party labs, catching issues before bulk production.

Needle & metal detector

100% of finished goods pass detection stations before packing.

Zero-defect commitment

100% Inspection & Needle Detection

Every finished garment passes symmetry and pull-strength testing, and all production lines are equipped with needle and metal detectors — zero tolerance for broken needles or metal residue, protecting infants at every boundary.

Before shipment, goods are inspected to AQL 2.5 and released with batch test reports (formaldehyde, pH, colorfastness, heavy metals and more), with third-party laboratory re-testing supported on request.

Trims Safety

Trim Safety & Anti-choking Engineering

Global requirements integrated into every high-risk component — buttons and fasteners engineered to protect infants.

YPK lead-free, nickel-free snaps

Meet the 70 N pull requirement for infant garments while eliminating lead and nickel contact risks.

Flatlock seamless seaming

Japanese Pegasus 4-needle 6-thread equipment avoids seam friction against sensitive infant skin.

Tagless heat-transfer care labels

Replaces woven labels with eco-friendly heat-pressing and low-allergen adhesives.

Quality Control Flow

Five-Gate Quality Control

From incoming fabric to shipment, five checkpoints fix the quality standard — every step traceable and re-testable.

01

Incoming inspection

Fabric and trims screened from our 500+ material library before cutting; certificates verified per batch.

02

Golden sample sign-off

PP sample and countersigned golden sample fixed as the benchmark at production QC stations.

03

In-line QC

Symmetry, seam quality and workmanship checked during production, not only at the end.

04

Final inspection + 100% needle detection

Every finished piece is inspected and passed through needle/metal detection before packing.

05

AQL 2.5 shipment & reports

Shipment inspection to AQL 2.5 with batch test reports issued for customs and platform onboarding.

Audit-ready documentation

Request Test Reports & Audit Certificates

Batch test reports, BSCI audit reports and certification documents are available on request — supporting brand and marketplace onboarding, with on-site or video factory audits bookable.
